INVENTOR FRANCIS H. BRATTON CONTAINERS FOR EXTRUDABLE MATERIALSREFERENCES The subject matter contained in this application is relatedto that in my applications entitled:

EXTRUSION PACKAGES FOR VISCOUS MATE- RIALS CAULKING GUNS OF IMPROVEDDESIGN FLOW CONTROL VALVE AND PRESSURE INDI- CATOR FOR VISCOUS MATERIALSYSTEMS and which are filed on even date with this application.

SUMMARY OF THE DISCLOSURE New containers for caulking and similarextrudable materials which may be operated by the application oftensile'force in the direction of extrusion are provided. The tensileelement is sealed with a close fitting plastic or metal seal, a plasticcoating on the element, or by a close fitting plastic or metal tube.Provision for the application of force for extrusion in differentdirections is made possible by formed portions of the containers andsimple units operating axially or transversely are described. A capsystem. to convert the cartridges to extrusion units and use of thecartridges in conventional caulking gun equipment is also described.

BACKGROUND OF THE INVENTION The present system and similar and improveddevices proposed under copending applications provide for the smoothextrusion of caulking and other viscous bead material with easily guidedand controlled equipment. The present units have self containedmechanisms which may be operated manually or with a power source. Thepresent system is designed for the precise deposition of uniform amountsof viscousmaterials for use as adhesives or as caulking material'and isdirected to provide a system which is operable with one hand.

In the present caulking practice both manual and power operatedcaulkingunits are providedwith'handles which are frequentlyvery remotely relatedvto the point of application'and whichthereforenecessitate the use oftwo hands for the guiding of. the deposition of the bead. The presentcartridge is arranged in part to provide a package which can be usedwith caulking guns which are designed for better balance and which willallow one hand operation from such places as the ends of ladders. Theyalso provide units which can be used to extrude material in crampedquarters without the interference of a large handle or of a largecaulking gun. In present practices much caulking material is supplied incartridges about 2 inches in diameter and "8% inches long which containabout" 10% fluid ounces of material. It is generally extruded with apressure gun which has a push rod which is advanced a step or a notch ata time by squeezing a lever associated with the handle. In othersituations material is supplied in bulk or in metal or plastic tubeswhich also present some similar problems in use.

Generally metal squeeze tubes can be used to extrude the material quiteeffectively. However, they are subject to occasional tearing orpin-holing and become somewhat damaged on dealers shelves and intransportation. They therefore present a cosmetic problem in handlingand shipping. The plastic squeeze tubes provide extremely attractivepackages but suffer in that the case of extrusion of the materialchanges markedly with the use of the contents. of the tube. As morematerialis removed the pressure required to obtain a smoothuniform beadbecomes increasingly difficult to maintain. These containers requirecontinual application of pressure from tightly clenched fingers, foldingof the slippery, resilient tube, and frequently require this in veryawkward positions. It is proposed in these situations to provide acontainer with a built-in takeup device which may be readily operatedwith one hand to permit smooth extrusion of the contents.

Effective, and where required quantitative, extrusion of material suchas toothpaste, adhesives, oil paints and pigments, food and seasoningsmay also be realized.

The present type cartridge containers may be handled in such a way thatthe size of the container may be reduced as the contents are used up.Flexibility is provided by these new containers as different sizedcartridges are compatible with a single pull type dispenser.

In addition by specific design it is possible toprovide cartridges whichallow for the simultaneous discharge of two or more viscous materials ina predetermined ratio. The handling of resin systems which requireactivation or catalysis for preparation for use and where the thecomponents are incompatible when stored for long periods of time requirethis mode of dispensing.

The present device also provides for simple changes in the amount offorce or the speed with which extrusion occurs by changing the effectivediameter of the windup shaft or drum with respect to the drivemechanism. Other considerations in the design of the extruder mechanismare considered and improvements are described in detail in my co-pendingapplications.

It is an object of the present invention to provide a container forviscous material which may be used with rigid containers of varyingdiameters which may be used for extruding materials of a range'ofviscosities.

It is the object of the present invention to provide a system whichincludes a guide for a tension filament in a pull-type extrusioncartridge which guides the filament and minimizes its movement withrespect to the sealing area at the end of the cartridge.

It is an object of the present invention to provide a container forextrudable viscous materials which may be smoothly operated manually orwhich may be driven by power tools.

It is'the further object of the invention to provide a pull-typecontainer which has extra filament available for easy attachment toseveral different types of extrusion devices.

It is an object of the invention to provide storage systems forextrudable materials in which long shelf life can be realized and inwhich corrosion is held to a minimum.

It is an object of the present invention to provide a cartridge systemwhich within a single cylinder may provide for the extrusion of two ormore viscous materials in controlled ratio by very simple mechanisms.

DETAILED DESCRIPTION OF THE DRAWING A number of specific examples ofways in which the present invention may be practiced are described belowand are presented to illustrate its embodiment but not to limit itsapplication.

EXAMPLE! The arrangement as shown in FIG. 1 illustrates the simplestprinciple of the pull-type cartridge. It consists of a rigid cartridge(1) substantially round in cross section which confines viscousextrudable material between a movable piston (2) and a rigid bulkhead(3). Contents of the cartridge may be caused to extrude through thespout (4) by the application of pressure to the piston in the usualmanner by exerting a pushing force behind it. The cartridge however isalso equipped with a filament of metal or plastic (5) which passesthrough a small hole (6) in the rigid bulkhead so that the contents ofthe cartridge may be caused to extrude by the application of tensileforce on the filament by any suitable method. Optional seals to preventleakage or spoilage may be provided as desired on either end of thespout but are not shown.

The use of the cartridge is readily visualized in a conventionalcaulking gun and is not shown. It entails the familiar operation ofapplying pressure to the piston while holding the front bulkhead fixed.

The container unit in FIG. 1 is shown positioned for extrusion by a verysimple windup device in FIGS. 2 and 3. This unit is made with the flange(7) designed to fit with the enlarged edge of the front bulkhead in thegroove 8) and is held by the nut and bolt (9). Tensile force is appliedto the filament (5) by rotation of the handle 12) of the windup rod (10)which is in turn held by the support (11). This action causes the pistonto extrude the major portion of the cartridge contents.

EXAMPLE II A cartridge arrangement similar to that in Example I is shownin FIG. 4. The filament (5) is connected to the piston and passesthrough a hole (14) which has been punched in a combination barrier ofmetal and plastic by an acicular instrument in a direction opposite tothat in which pressure is exerted to cause extrusion of the contents.The hole (14) is located in the center of the barrier (3) to allowsubstantially complete extrusion of the cartridge contents. A pulley(13) is provided so that the filament may be pulled in a directionperpendicular to or opposite to the direction of extrusion.

EXAMPLE Ill The cartridge arrangement shown in FIG. 5 as in the case ofExample Il may require minor revision or minor modification of thethrust barriers of some conventional caulking guns. In this example anextra (15) length of filament has been provided for convenience. Thefilament has been coated in this case with soft plastic material (16)whose diameter is slightly greater than that of the hole (6) in therigid bulkhead to provide an effective seal during the extrusion of thecontents. The soft coating (16) also acts as a lubricant in the passageof the filament (5) over the formed hump (17) de signed as a formedprojection over which the filament may be pulled. This is provided topermit the applicav tion of tensile force in a direction different fromthat in which the contents are being extruded. It has also been foundthat with many metals that the frictional forces do not greatly impedeextrusion. Brass, copper and steel alloys pass freely over tin platedsteel.

EXAMPLE 1v EXAMPLE V This example shown in FIG. 7 follows the basicsimilarity of the earlier examples. The piston (2) is attached to afilament (5) which is sealed by a plastic bushing (21) and which passesover the hump (19). It may be put into tension by rotating the externalaxial windup rod (22) which is driven by a knurled knob (25) and whichoptionally may be supplied with external power from a device such as anelectric drill or gear motor by the power shank (26). It will beappreciated that the rod may be attached to the container by clamps orsupports (24) or may be inside a tube or housing. It may be supplied asa separate removable and reusable unit or may be built as a feature of adisposable caulking container or dispenser. The rod may contain asection with an increased (or decreased) diameter rod such as is shownin the increased diameter (23) in FIG. 7 and which alters the mechanicaladvantage associated with the windup mechanism. The windup mechanism maybe provided with a ratchet or other device to prevent backlash.

EXAMPLE VI FIG. 8 illustrates a simple clamp-on extrusion deviceconsisting of a windup rod (22) inside a guard tube (27) which serves asa bearing and to which are attached the clamps (28) for affixing it tothe cartridge.

The filament (5) is wound by turning the knurled knob with the fingers,with the folding crank (29), or with the application of power to theshank (26).

EXAMPLE vn Example VII shown in FIGS. 9 and 10 illustrates amulticompartment pull-type extrusion container in which an opening (30)is provided through which a windup rod (22) passes through the cartridgeor assembly, By turning 22) the filaments (5) and (5A) are put intension and the semicircular pistons (2) and (2A) are moved forward tocause simultaneous extrusion of equal quantities or a predeterminedratio of the components in the compartments. The present example, shownfrontally in FIG. 10, illustrates the flow from two separate spouts (4)and (4A) which might also be provided with a mixing chamber as they aredischarged. The spouts may be replaced with small holes located in closeproximity to each other. In the present example the semi-cylindricalunits are provided with separate flat walls (31) and (31A but may beprovided with a common septum. The filaments pass over the formed humps(l9) and (19A) to be wound in the rod (22).

EXAMPLE vm A. simple extruder attachment is shown in FIG. 1 1 and showsthe use of a thumb operated windup rod perpendicular to the axis of thecontainer. The filament (5) may be wound on the rod (32) by thereciprocal action of the thumb lever (33). The mechanism is held inplace by the clamp (34) and permits one-handed operation of the caulkingunit.

EXAMPLE IX diameter. The rod is held by the mechanical chuck (39) whichis tightened to prevent slippage of .the rod. The support cradle isdesigned to eliminate point loading of the cartridge and is providedwith a support area of a radius essentially equal to that of thecartridge being used. Suitable mechanical speed reducers and/or powerfulelectric drills or pneumatic drills are preferred and must be used ifthe diameter of the cartridge is larger or if the viscosity of theextrudable material is high.

EXAMPLE X Example X shown in FIGS. 13 and 14 provides a very simpleself-contained unit which may ha e a tensioning cap (40) supplied withit or provided as a separate item. The cap fits onto the end of thecartridge which is provided with some rigidity and applies tension tothe filament (5) by engaging it in a wire holder (42), Passing itbetween two of the protruding projections or knobs (43) of the cap, andthen turning the cap. As the cap is turned to a new position out of theplane of the hump (14), or other guide, a new position may be realizedby taking up some slack in the filament by either pulling it furtherthrough the wire holder (42) or by hooking it over some additionalprojections (43) as shown in FIG. 14. The cap is provided with an areaof reduced diameter (41) designed to fit snugly into the cartridge. In adevice such as this the knobs may be made very small and essentiallybecome separations between groves through which the wire passes. Such amechanism may easily be provided as a throwaway item associated with thecaulking container.

The design and operation of the examples described above may make use ofthe flow control/flow indicator tip cartridges as described under myco-pending application FLOW CONTROL VALVE AND PRESSURE INDICATOR FORVISCOUS MATERIAL SYSTEMS, but is not necessary.

It will be understood that the specific sizes, the materials ofconstruction, means of fabrication such as lamination, crimping,rolling, gluing, riveting, welding and the nature of the extrudablecontents may be varied over considerable latitude as now commonly occursin application of caulking, adhesives, sealants, lubricants, and thelike. Improvements provided earlier by others may be incorporated andmay include spout seals, reinforced or structured pistons, optimum.strength wall structures and similar features.
